Crystal structural and photoluminescence properties of Eu3+ doped MgZn2(PO4)2 phosphors by R+ (R = Li, Na, K) charge compensation

“…14,15 It is known that rare earth ions, such as Tb 3+ , Sm 3+ , Tm 3+ , Dy 3+ , Ho 3+ , Yb 3+ , Ce 3+ , and Eu 3+ , as activators are added to different substrates owing to their high emission performance. 1–4,8,9,12–26 In recent years, phosphate compounds single-doped or co-doped with rare earth ions have played a critical role in the development of phosphors. 1–24 Therefore, the luminescence properties of phosphors with various colors have been improved.…”

It is well known that trivalent europium (Eu 3+ ) with a 4f 6 electronic configuration leads to an intense red emission due to the 5 D 0 → 7 F 1,2 transitions in a variety of host materials.…”

“…It is well known that trivalent europium (Eu 3+ ) with a 4f 6 electronic configuration leads to an intense red emission due to the 5 D 0 → 7 F 1,2 transitions in a variety of host materials. 17–34 So many studies about the Eu 3+ -doped in tungstate, phosphate, silicate, borate, and oxide have been reported, 16–24 e.g. , BaZn 2 (PO 4 ) 2 :Eu 3+ , Sr 3 Sc(BO 3 ) 3 :Eu 3+ ,Bi 3+ , Ca 2 ZnSi 2 O 7 :Dy 3+ ,Eu 3+ , NaLa(WO 4 ) 2 :Eu 3+ , Sr 3 WO 6 :Eu 3+ , and Ca 2 GdSbO 6 :Eu 3+ phosphors have been synthesized.…”

The synthesis, structure, photoluminescence properties, thermal stability, energy transfer mechanisms, quantum efficiency, and others of them have been studied.…”

Efficient energy transfer from zinc oxide nanocrystals to europium (3+) and terbium (3+) ions embedded in an oxide matrix

“…Thus, the concentration quenching process increases with increasing concentration of the dopant atoms (or ions) which results in the reduction of luminescence from the excited dopant atom (or ion). [61] and Y 6 WO 12 [62] were used in these studies to improve the radiative emission from the lanthanide ions, namely Eu 3+ and Tb 3+ .…”
